Here's the image of my possible setup. The main growing chamber is two stacked 18'x24' storage bins. The red circles will be holes drilled into the top of both bins and to the bottom of only the top bin. This will allow air movement throughout the entire setup. The white indicates the level of perlite that is to be added to the base of each bin. Perlite will not fall through the hole in the topmost bin due to a piece of tubing that will fit snuggly into the hole. The blue box to the left will be an ultra-sonic humidifier (2.8 gallons) and will most likely be set on a timer to go off at certain intervals. The other blue section which conects the u.a.h. to the setup will be simple collapsable tubing, like you see being used with exhaust systems for large hid lighting systems. Finally, the green indicates where the cakes will be. Obviously I can fit a lot more than four in these bins, but you get the idea. Hopefully this setup is something that's feasable. I'm going to try constructing it over the next few weeks.

to answer your first question where to keep the jars full of colonizing substrate? you said you have an "incubator" but i think you ment "terrium" b/c the pic of your setup with the u.h. is where the fruiting will occur. like and egg, the jars are keep in a warm dark undisturbed place to incubate.

then once the jar is overtaken by the mycellium. you pop it out and either case it or put it into your terrium. im guessin your just gonna go with straight up cakes since up bought a u.h. but you have like a dual over-under type terrium with two fruiting chambers. im not to familiar with building exauhast ports and yak smak. i use a 14 gal rubber maid container with a light hole cut out of the top. aand only like 1 1/2 to 2 inches of perlite. the if your using a u.h and it can keep a constant hum of 90% skip the perlite. because with perlite alone there is enough hum. soak it down in a speggetti strainer then put into terruim. hope i helped but ill check back if still more ?'s

Okay, this is what I'm gathering...I should inject the spores into the jars and put them in an incubator, but without keeping the humidity too high because the spores are colonizing, not fruiting. Once the entire jar is colonized, I keep them in the incubator but now make it humid. I plan on buying an ultra-sonic humidifier, so any suggestions with that would be greatly appreciated due to my inexperience with them. I'm also to understand that I should in fact put perlite at the base of my incubator to catch any excess water that may drip down the sides of the incubator. If I'm wrong at any point here, please let me know. I should also be able to post an image of what my setup will hopefully look like so you can get a better idea of what I'm dealing with.

I think I may just put in some perlite, add some water and maybe a few tap-lights. Also, if tap-lights don't generate much heat (and I don't think they do) then I can put down a 12x24 soil-heating mat (made for litely heating the rockwool marijuana seedlings grow in) under the perlite. Its waterproof so leaks into the mat wouldn't be an issue. And if it heats too much at once I can set the mat to go on and off via a timer. By the way, how many jars do you think I could fit into an 18x24 bin while they're in their fruiting period?

my friend found his jars at a hardware store (12 for $8). they were 1/2 pint (8 oz.) and tapered just like the MMGG calls for. check the grocery stores or walmart if you cant find 'em at a hardware store.

808 I hope you got the point that you don't need to use perlite or worry about the humidity until you birth the cakes and put them in a grow chamber. Also judging by your questions I would stick with perlite as a humidity source. It is much simpiler as long as you don't have to leave the grow chamber unattended for a more than a day or so.

yeah, i get what you're saying. i only questioned using perlite becuase i'd be using 20 jars at a time and i figured that due to the larger scale i may need a better source of humidity. however, most everyone has obviously told me otherwise, so i guess i'll just stick to using perlite. how often do you change the perlite though?

Here's what you do 808. Read the MMGG. It sounds like you haven't done that yet. You are asking a lot of silly questions. You don't ever need to change the perlite in your terrarium unless you drop a lot of crap into it and it turns into a big mess.

i've actually read the mmgg and as good as it is, there are some aspects of growing that it doesn't bother to mention. i prefer to get the facts up front so i can get it right the first time instead of dicking around until i stumble across the best method. so sorry if i'm wasting your precious time but i'm not twisting your arm to answer my questions. in the future, you may try being a little kinder to beginners and a tad less inept.

That pretty much tells me right there that you havent read anything thoroughly. I don't flame people often, but you really should read more before posting such stupid (yes, stupid) questions. Read some other teks too for a greater overall feel.

vorpal isn't inept. every time i ask a ?, whether it's stupid or not, he answers and it's always polite.....but anyway, i know the teks don't tell us everything,but the questions you ask ARE answered in teks. have fun, and good luck

If you use perlite air exchange will be a pain with that stacked setup. If I were u I'd go with a cool mist. With perlite in the bottom chamber only. Make an exhaust holein the lower chamber for co2. And I'd read alot more.
